I am a reflexologist and holistic health practitioner. Prior to this I have also worked in health stores for nearly 10 years and received a huge amount of training in nutritional supplements. Having had two concurrent kidney infections and the nasty antibiotics to accompany them I really wanted to find a good urinary aid supplement to help maintain kidney and bladder health. This is an excellent product that meets German health standards. I initially took two both morning and night for a week and now take two in the morning, first thing with a mug of warm water on an empty stomach. So far so good no recurrence of the infections. Golden Rod is excellent for the kidneys and it also contains Solidago also great for the kidneys and Uva Ursi for bladder health. This is one product that I will be sticking with. I make sure to drink lots of water as well. I hope you found this review helpful.
